zenof the United States, residing at Dar lington,- in the county of Darlington'and` 5 Be it known thatfL'EUenNiiBAimn, a citi- Stateof South. Carolina, have invented new land' useful-J Improvements -in Motor-Vehicle The. pnesentfitiv'ention, has for its object .tondevisenovel means whereby power may be positively applied to tlie steering`\vheels :lof-.a mechanically driven` vehicle 'for proipelling the same. A'

The advantages resulting from apply? ing power to all the wheels of an autonie-v bile'or like -motordriven vehicle are manifest, chief among whichnar'e a uniform' dis'- tribution of the wear uponthe tires, equalization of the tractive foree,: whereby lslipping is prevented and the machine 'caused to run more smoothly and a greater diiu-v s ion of the stra'in throu l hout the chassis and A,

running gear 0j the v e icle.

The presentI invention provides a novel structure of hub for the steering wheel, a

- peculiar formation of steering knuckle and a special construction of gearing and adjunctive parts to admit of the steerintg wheel turning reely and at all stages o movenient having power positively applied thereto.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more lparticularly set -forth, illustrated' in the accompanyin drawings, and pointed out in the a. pen ed claims.

Rei'erri ng to the drawings, formin a part of the appiication, Figure 1 is a si e View of the huli Jortion of a steering wheel of an automobile embodying the invention, the axle and it; supporting shaft being in section.

v cated. in all the views ofthe drawings, 'by

outwardly extendingportion of the hub..

The hub 1 is of larger diameter than usual and. is provided with an opening 3 forming a segment of asphere, the end portions be ing cutaway equidistant from a planepassing centrally through the sphere. The inner wall 'of tlieopening 3 has teeth 4. The inner end of `the hub is open, as indicated at 5, whereas the outer end.y is Vclosed by .a wallf-romwhich extends outwardly a bearing 7,. which receives' the spindle 8^upon which the Wlieelis mounted. The axle is indicated at 9 and. is mounted in a 'sleeve 11. A knuckle joint is-'provided between the spinld'le 8 and the axle'), the knuckle members forming parts of the spindle and axle sup' porting sleeve. The axle supporting sleeve 11 is fixed and the axle 9 is mounted therein toturn freely and has a pinion 12 fastened thereto, said pinion meshing with a gear wheel 13, which in turn meshes with the teeth 4 of the hub 1. A frame 14 is provided at the outer end of the axle support l1 and the' axle ismounted'therein as also the gear wheel 13. hThis frame 14 constitutes the fixed member of the knuckle joint.

An arm 15 has connection with the spindle 8 and forms an extension of the movable member of the steering knuckle. The arm 15 has a portion composed of spaced parts 16, which are oppositely curved to extend over and below the frame 14, as indicated most clearly in Figs. 4 and 6. Pivot fastenings 17 connect the spaced parts `1G of t e arm 15 with upper and lower portions of t ie frame 14. The pivot fastenings 17 ara-in a plane passing through the center of the sphere of which the opening 3 is a se ent. The frame 14 has a flat circular portion 18,

which is arranged-iii a horizontal plane and is located centrally between the spaced por- The arm 15 at'the juncture of the spaced portions 16 with the spindle 8 has a notch 19 in which the outer edge of the flattened circular portion 18 enters, thereby materially strengthening and stiiening the knuckle Joint without interfering in any manner with the free pivotal movements of 'the spindle when the same is turned by means of the steering control.

It is to be understood that the gear wheel 3 i of the method of Know consider to be the \therefor having a horizontally'dispos cular portion, a spindle 13 is at au times in mesh with the @eine constituting the gearing forming part of the` ,i axle to the steering wheel to. assist materially in propelling the vehicle.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and operation Will be readil apparent to those skilled in the art to whic the invention appertains, and while I have described the principle of operation of the ',invention, together with the device which I v embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made whendesired as are Within the Scope of the'claims appended 29 hereto.

Having thus described the invention what is claimed as new, is:

1. In combination a drive axle, a su port.

circonnected with. the frame of the axle support by means of a knuckle joint and having a portion engaging the outer edge of said circular portion o and gearing theaxle support frame, a wheel hub mounted upon the spindle and having a spherical shaped opening toothed upon its inner Wall, connected with the drive axle and mounted upon the frame of the axle support and in mesh with the teeth upon the inner wall of the spherical opening of the wheel hub. e

2. In combination a drive axle, an axle support, a frame at the outer end of the axle support,'a spindle, asteering armhaving connectidnjwith the s ndle and comprising. spaced portions whic embrace upper an lower sides of said frame and are 4pivoted thereto, a wheel hub mounted upon the spindle and having a spherical shaped opening toothed upon its inner walls, and gearing connected with the drive axle supported b `the frame of the axle support and in mesh with the teeth upon the inner wall ofl the spherical shaped opening of the wheel hub.

In testimony whereof I affix my signaturo in presence of two witnesses.
